After the inspection is completed, continue to tighten the sliding sleeve 401 and push the sliding closing plate 3 upward until the limit plate 5 and the lower surface of the mounting plate 1 are in contact. Then release the sliding sleeve 401. The sliding sleeve 401 will slide into the matching hole 301 on the sliding closing plate 3 under the push of the spring 404, thereby limiting the movement of the sliding closing plate 3 and completing the closure of the open end of the protective frame 2.
